The Mediterranean non indigenous ascidian Polyandrocarpa zorritensis: Microbiological accumulation capability and environmental implications.
Full text linkWe investigated the bacterial accumulation and digestion capability of Polyandrocarpa zorritensis, a non- indigenous colonial ascidian originally described in Peru and later found in the Mediterranean. Microbiological analyses were carried out on homogenates from “unstarved” and “starved” ascidians and seawater from the same sampling site (Adriatic Sea, Italy). Culturable heterotrophic bacteria (22 °C), total culturable bacteria (37 °C) and vibrios abundances were determined on Marine Agar 2216, Plate Count Agar and TCBS Agar, respec- tively. Microbial pollution indicators were measured by the most probable number method. All the examined mi- crobiological groups were accumulated by ascidians but differently digested. An interesting outcome is the capability of P. zorritensis to digest allochthonous microorganisms such as coliforms as well as culturable bacteria at 37 °C, counteracting the effects of microbial pollution. Thus, the potential exploitation of these filter feeders to restore polluted seawater should be taken into consideration in the management of this alien species
Settlement and population dynamics of the alien invasive Branchiomma bairdi (Annelida: Sabellidae) in the Mediterranean Sea: two years of observations in the Gulf of Taranto (Italy)
No full textSince the first discovery along the Italian coasts in 2004 of the polychaete Branchiomma bairdi, it
has spread very quickly, reaching some localities in very high densities. In order to monitor its
colonization, recruitment was investigated by means of PVC panels immersed in the Mar
Grande of Taranto (Ionian Sea). Panels were monitored every three months from April 2013
to January 2015. The species showed the ability to settle on bare panels as well as on panels
with a developed fouling community. Two years of monitoring identified two different
cohorts, with recruits appearing in both years on panels submersed from July to October.
Based on these observations B. bairdi is a short-lived species (no more than one year),
reproducing at a temperature ranging from 20 to 29°C and reaching sexual maturity three
months after recruitment. Oocytes were found in the coelom only in the warmest months
and oogenesis was not synchronous either within each individual or within the population.
Total annual secondary production was estimated at 43.42 g m−2 year−1. Annual mean
biomass was 20.03 g m−2. The corresponding P/B ratio was 2.1678. This study may explain
the invasiveness of B. bairdi; indeed, a rapid generation turnover coupled with a short
lifespan, rapid growth and early maturity are common traits in most invasive species
Iphinoe elisae Bacescu 1950
No full textIphinoe elisae Bâcescu, 1950 Material examined. 2 ovigerous females, st. 2; 1 ovigerous female, 1 adult male st. 26; 1 ovigerous female without uropod, st. 39. Remarks. Iphinoe elisae was described by Bâcescu (1950). It is characterized by four perianal setae, like I. serrata. However, I. elisae only has one aesthetasc on antenna 1, while I. serrata has two. These traits are common for both male and female specimens. The adult females observed from station 2 have four setae in the first uropod segment as do the males, rather than three as described by Ledoyer (1965). The integument is covered by scarce bristles. Distribution and Ecology. Iphinoe elisae is a common species in the Black Sea (Băcescu 1950; Revkov et al. 2002; Kirkim et al. 2006; Todorova & Konsulova 2006; Dumitrache et al. 2013), but has also been reported from the western Mediterranean (Sánchez Moyano et al. 2012). Up to now, I. elisae had not been reported from Italian waters. Here we report its presence in area 9 (Table 3). Iphinoe elisae was first discovered in muddy sediment at a depth of 30–80 m in the Black Sea (Băcescu 1950). Kirkim et al. (2006) recorded I. elisae on the Anatolian coast in both mud and fine sand sediment; Sánchez Moyano et al. (2012) in the interior of Algeciras Bay (Spain), and in Caulerpa prolifera meadows (2–5 m deep). A specimen of Iphinoe elisae was found in our samples on biocenosis with 60% of sand, at a depth ranging between 2 and 39.5 m (Table 1).Published as part of Mazziotti, Cristina & Lezzi, Marco, 2020, The cumacean genus Iphinoe (Crustacea: Peracarida) from Italian waters and I. daphne n. sp. from the northwestern Adriatic Sea, Mediterranean, pp. 331-357 in Zootaxa 4766 (2) on page 345, DOI: 10.11646/zootaxa.4766.2.4, http://zenodo.org/record/376409
Streblosoma Hutchings and Glasby 1987
No full textStreblosoma Hutchings and Glasby 1987: 222. Type species. Grymaea bairdi Malmgren, 1866, by original designation. Diagnosis Transverse prostomium attached to dorsal surface of upper lip; basal part usually with eyespots; distal part low, restricted to base of upper lip. Buccal tentacles all uniformly cylindrical. Peristomium forming lips, sometimes continuing dorsally as narrow annulation, with nuchal organs as thin ciliated row on anterior margin; short, hood-like upper lip, about as long as wide; lower lip also short, button-like, restricted to oral area. Short anterior segments, usually visible all around body, segment 1 frequently with ventral lobe posterior to lower lip, lobes on following anterior segments absent. Branchiae usually present, 2–3 pairs beginning from segment 2, each pair with numerous independent curled filaments, progressively tapering to tips, mid-dorsal gap between filaments of each side within pairs either present or absent. Anterior body highly glandular ventrally, swollen, smooth to strongly tessellated. Notopodia beginning from segment 2, extending for variable number of segments; conical and relatively short notopodia, distally bilobed, chaetae emerging between lobes. Winged notochaetae in both rows, those from anterior row broad-winged in several species, with wings somewhat twisted. Neuropodia beginning from segment 5 as fleshy ridges anteriorly and as raised pinnules after termination of notopodia. Neurochaetae throughout as short-handled avicular uncini, with dorsal button at anterior third of base or terminal, prow, if conspicuous, usually distinctly short, and strongly curved, convex base in most taxa; uncini usually in single, straight rows, a few species with uncini arranged in curved C-shaped to looped rows. Nephridial and genital papillae usually present, posterior to bases of notopodia of segments 4–7. Pygidium smooth to slightly crenulate (Hutchings et al. 2015, 2017).Published as part of Lezzi, Marco & Giangrande, Adriana, 2019, New species of Streblosoma (Thelepodidae, Annelida) from the Mediterranean Sea: S. pseudocomatus sp. nov., S. nogueirai sp. nov. and S. hutchingsae sp. nov., pp. 2857-2873 in Journal of Natural History (J.

Iphinoe crassipes Hansen 1895
No full textIphinoe crassipes Hansen, 1895 Iphinoe crassipes Hansen, 1985; p. 53–54. pl. 16 fig 4a–f. Not Iphinoe crassipes haifae Bâcescu, 1961; p. 501 fig. 3D, 4. Not Iphinoe crassipes Day, 1978; p. 224–230, fig. 26–27. Remarks. The status of I. crassipes was clarified by Corbera (1994) who presented a new description of the adult male. Previous descriptions of I. crassipes (Hansen 1895) and I. crassipes haifae (Băcescu 1961) had been based on preadult males. The species differs from other Mediterranean congenerics in that it has two terminal aesthetascs on antenna 1. Moreover, the dorsal carina is unarmed in males (Corbera 1994) and the CL/CD ratio is about 1.5. Morphological data on female specimens are not available. A truncated pseudorostrum and a pair of lateral carinae are further diagnostic characters of I. crassipes. Distribution and ecology. Iphinoe crassipes (sensu lato) is present in the western Mediterranean Sea (Corbera 1994) and in the Levantine sea (Bâcescu 1969). Its distribution is typical of a circumtropical species Corbera (1994), although Băcescu (1961) explained the record of I. crassipes haifae from the Israel coast as a possible invasion through the Suez Canal.At first Corbera (1994) casted doubt on this hypothesis, based on the occurrence of this species off the northeastern coast of the Iberian Peninsula (Catalogna coast). However, after a finding in a new western Mediterranean locality (along Valenciana coast) Corbera (2015) suggested that this disjunct distribution could be a shipping introduction way. The species has never been reported from the Italian coast, nor was it found in our samples. Corbera (1994) reviewed the ecology of Iphinoe crassipes (sensu lato), reporting that the species lives in warm temperate waters (Hansen 1895, Jones 1956, Le Loeuff & Intes 1972, Day 1978) such as the western coast of Africa, and avoids the cold upwelling zones (South Africa and Mauritania coasts). Corbera (1994) found this species in sandy bottoms at a depth of 15 m.Published as part of Mazziotti, Cristina & Lezzi, Marco, 2020, The cumacean genus Iphinoe (Crustacea: Peracarida) from Italian waters and I. daphne n. sp. from the northwestern Adriatic Sea, Mediterranean, pp. 331-357 in Zootaxa 4766 (2) on page 338, DOI: 10.11646/zootaxa.4766.2.4, http://zenodo.org/record/376409
